Game Boy Advance AGS-101 Voltage Regulator

Retro Modding
| /

Our in-house voltage regulator is now available for your custom modding projects. 

On its own, the Game Boy Advance doesn’t feed the AGS-101 enough power, meaning it's not as bright as a backlit GBA SP. Our in-house VR provides the appropriate voltage and current to produce a clear backlit image. It's so bright you can even play in the full sun! With greater stability and a compact size, it's never been easier to mod your Game Boy Advance.

For more control, upgrade to our VRV2, which combines our voltage regulator with our in-house brightness controller.


  • Dramatically improves the brightness of the AGS-101 LCD by supplying the appropriate output voltage of 12.2V
  • Operating voltage between 1.7V and 3.2V (meaning no flickering with low batteries)
  • Supports software-based sleep mode included in select games (Super Mario Bros. 3, Zelda, etc.) through low-power mode
  • Smaller footprint than similar boards (9.2mm x 13mm)
  • Simple four-wire installation
  • Pre-wired board includes wires of the appropriate length already soldered to the board, as well as heat shrink tube and mounting tape already installed


  • Dimensions: 9.2 mm x 13 mm x 3.2 mm
  • Input Voltage: 1.7 to 3.2 V
  • Output Voltage: 12.16 V
  • Termination: Solder pads

    Ordered parts

    I have not had a chance to use it as I did not purchase a AGS-101 Screen so i did not need it. but the Helder's Game Tech GBA Power Cleaner works great

    Perfect product and customer support

    I installed this board in a GBA SP AGS-001 for use with an AGS-101 screen.
    The support was even able to answer my specific technical questions about the product which is pretty unusual for online purchases!
    A cool Retro Modding sticker was inside the package, too :D
    I will definitely buy here again.

    For anyone wanting to put this in an AGS-001 just as I did, you can see how I did it here:
    Note that the brightness button of the GBA SP loses its effectiveness and is now switching between full brightness or no brightness (which then looks like the display is turned off) when pressed.

    Does exactly what it advertises.

    If you need maxiumum brightness on your 101 mod look no further. I installed this for a customer with a vision disability and hes still writing to me raving about how much this has improved his gaming experience. You will need to figure out your own way to regulate the voltage but if your like my guy and need it at 100% all of the time this is a simple and easy way to get it done.
